WALKING BEAM. I

Application fil ed May 4,

The invention relates to walking beams, and has for its ob ect to provide a device of this character with cushioned truss rods,

whereby shock and jar incident to the opera 5 tion of the device are absorbed, thereby insuring an easy operation and a beam which Wlll havea flexible springing motion, conse quently breaking of the drilling rope is obviated, V y

A further object is to provide theunder portions of the end of the beam with transverse plates anchored in recesses thereof, and extending beyond the opposite sides of the beam, and to which plates the ends of the truss rods are anchored, thereby positively anchoring the truss rod ends to the ends of the beam. Also to provide the inner sides of the plates with inwardly extending ribs engaging in channels in the beam ends for additionally anchoring the plates against dis placement. V A

A further object is to provide the upper side of the beam with an upwardly extending dome terminating in a cap plate, through whichvertical rod ends extend and cooperating link members on the cap plate, atopposite sides of the vertical rod ends, and to which the adjacent ends of the truss'rods are anchored. The link members beingadjustable 3 in relation to each other whereby the tension of the truss rods maybe varied.

A further object is to interpose between the dome and the cap plate a'resilient member, for instance a rubber cushion, which is comthereon for allowing aspringing action of the beam within the limits of the truss rods.

A further object isto form the dome from adjacent cylindrical members supported on the beam, and through which the vertically disposed rods extend, a plate on the upper end of the cylindrical members, and which plate is held in close engagement with the upper end of the cylindrical members by means of nuts on the vertically disposed rods,

a plate having nut receiving apertures therein, and through which the vertically disposed rods extend, and which prevents rotation of the nuts, a plate engaging the upper side of the nut holding plate an'd'on which the resilient member is disposed and a convened crown plate on the top of the last named plate, which crown plate is preferably upwardly convexed.

A further object is to provide the upper sides ofthe ends of the beam with plates for [through the pressed by'the cap'plate incident to strain 1927. swarm. 188,741.

the reception of the rod rope end and the rig I loop, which plates have in connection there with yieldable'means for additionally taking up the shock incident to the operation of the device. a

' With theabove and other objectsin view,

the invention resides in the combination and I arrangement of parts as hereinafter set forth,

shown in the drawing, described andclaimed,

it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing form the spirit of the invention. I r i In the drawing beam. V Figure 2 is a topplan view of the walking beams Figure 3 is a vertical transverse sectional alk ng beam taken on view through thew line 33 of Figure 2. @Figure 4: is a horizontal sectional view 3 dome taken on line of Fig ure 1 7o Figure 1 IS a side elevation of thewalking Figure 5 is a bottom perspective'view of one of the walking beam ends. v

Figure 6 is a'perspective View ofjoneof the transverse platese 1 Referring to thedrawing thenumeral 1 designates the'b'o'dy of the walking beam which. is wider at its centralpoint than at its end and is adapted to reckon any suitable supporting means at'the point a; 'Extending upwardly through'the beam 1" centrally thereof and intransverserelation arespaced vertically disposed rods 2, whiclrrods are preferably provided with heads, 3 disposedin recesses a in the under sides of thefbeam 1.

"Disposed on the upper side of the'beam 1 is abase plate 5, on which rest the'lower ends of vertically disposed cylindrical members 6, which cylindrical members are bolted to gether by means of bolts 7 for preventing displacement in relation to each other. Disposed on the upper end of the cylindrical members 6 is a transverse cap plate 8', and it will be noted that the vertically disposed rods 2 extend upwardly through the bearn l, base plate 5,,cylinders 6 and cap plate8, and provided with threaded ends 9 onwhich are threaded nuts 10, which'wvhen tightenedagainst the cap'plate 8,'force s the cap plate into close bin-ding engagement with the upper ends of the cylinders 6 and force saidcy'lin ders downwardly into close binding engagement against the plate 5, which in turn is forced into binding engagement with the upapertures 12 conforming substantiallyto the shape of the nuts 10, and not only serves to add strength and a slight resiliency but also as means for preventing retrograde rotation of the nuts 10 after they have been adjusted to proper tension, therefore it will be seen that after the nuts 10 have been adjusted and the parts assembled, that loos'eningof the nuts is obviat'ed.

Disposed on the upper side ofthe filler member 11 is a plate 13, which forms a bed or seat for a resilient member 14 which is preferably formed from rubber whereby a yielding and extending action is insured for the transversely disposed crown plate 16, which crown plate is transversely bent 4 and has its opposite ends 17in engagement with the resilient member 14, whereby there will be a springing action of the crown plate 16. The threaded rods 2 extend upwardly through the plate 13, resilient member 14 and crown plate 16 and may be provided with nuts 17 if desired, the purpose of which will be presently described.

The under sides of the outer ends of the beam 1 are provided with angled portions 18 hav ng transverse recesses 19 therein.

and disposed in said recesses 19 are transverse plates 20, which platesare provided with V-shaped ribs 21, which are received in the V-shaped recesses 22 in the bottoms of the recesses 19, thereby positively preventing displacement of the plates. Plates 20 are preferably provided with apertures 23 for the reception of securing means. Theends of the plates 20 extend beyond the opposite sides of thebeam land areprovided with apertures 24 which 7 receive therein the ends 25 of the truss rods 26, and which truss rods incline upwardly and inwardly and terminate in eyes 27, through which extend the arms 28 of the rightangled shaped links 29, and which links have one of their arms extending through the eyes 30 of the arms 28 and provided with nuts 31, which when tightened tension the truss rods 26. It will be noted that the right angularly shaped links 29 are at opposite sides of the upper ends of the-vertically dis posed: bolts 2, consequently said bolts will prevent lateral displacement of the links. The nuts 17 engage the upper sides of the links and if desired may be tightened into close bindingengagement with the links after the links have been properly adjusted thereby additionally bracing the same, but at the same time the nuts will not prevent the compressing of the yieldable member 14L by the crown plate 16 incident to shock or jerking during the oscillation of the beam. It will be noted that the truss rods 26 incline upwardly and inwardly from opposite sides of the ends of the beam and over transversely disposed members 32 which extend beyond the opposite sides of the beam, and which members 32 brace the truss rods and form a bearing point for one side thereof, thereby preventing excessive vibration thereof during the flexing of the beam, and during the compressing and expanding of the yieldable resilient member lei.

One end of the beamis provided with superimposed plates having a yieldable layer plates receive the usual loop and the plates designated by. the numeral 34. The yieldable layer 33 additionally absorbs the shock incident to the operation ofthe beam, consequently relieves the straincto a certain extent on the. drilling rig. The other end of the beam 1 isprovided with superimposed plates 35 having a layer of yieldable material 36 therebetween, and the end of the beam andplate as well as yieldable material is provided with a slot 37 for receiving the drilling rod or otherattachment. V I

From the above it will be seen that awalk ing beam, is provided for oil well drilling rigs, which beam is positively braced and trussed in a manner whereby it may flex within limits, thereby .relieving the sudden to the rig or mechanism to aminimum.

of material 33 therebetween, and whic'lr The plates 20 may be additionally held in place by means of tie bolts 40. I
